I am a board-certified Psychiatric Mental Health Nurse Practitioner and Family Nurse Practitioner with over 15 years of experience in healthcare. I work with adolescents, teenagers, and adults navigating anxiety, depression, stress, trauma, mood disorders, life transitions, and emotional burnout.

My goal is to create a safe, supportive, and judgment-free environment where clients feel heard, respected, and empowered. I understand that mental health is deeply connected to daily life, relationships, culture, and personal experiences, and I take a compassionate, whole-person approach to care.

I’m Thomas Moore, LPCC, a licensed professional clinical counselor providing therapy for individuals navigating anxiety, trauma, emotional overwhelm, identity development, and complex relational patterns. Many of the people I work with feel stuck in repeating cycles such as overthinking, people pleasing, emotional shutdown, intense reactions, or difficulty maintaining stable relationships even when they logically understand what they should do. My goal is to help you translate insight into real change.

My approach is structured and compassionate. I integrate evidence based methods including cognitive restructuring, emotional regulation training, interpersonal effectiveness skills, and trauma informed therapy. Sessions focus on understanding why your brain reacts the way it does and building practical tools you can actually use outside the therapy room. This is not only about talking through problems but learning how to respond differently when they show up in real life.

I work well with clients who want more than passive support and are ready to build skills, increase self awareness, and interrupt patterns that no longer serve them.

What clients should know before starting

Therapy with me is collaborative and active and you will learn strategies rather than only venting. We will work on understanding both the emotional and neurological side of your reactions. Sessions focus on present day functioning while also addressing past experiences that still affect you. I may gently challenge patterns when it supports growth while maintaining a supportive and respectful space. Progress often comes from small repeated changes rather than sudden breakthroughs.

If you are looking for therapy that combines validation with practical change, we will likely work well together.

My name is Dianne Fontaine, MSN, APRN, and I'm a Licensed Psychiatric Mental Health Nurse Practitioner, Board Certified (PMHNP-BC) by the American Nurses Credentialing Center (ANCC). I obtained my Master’s Degree from Walden University and has undergone advanced clinical training, equipping me to assess, diagnose, and treat a spectrum of psychiatric illnesses, as well as provide psychotherapy.

If you have tried therapy before without the results you hoped for, you may need a more targeted, effective approach. Over the past 15 years of my practice as a clinical psychologist, earning your trust and helping you establish a secure, empowering baseline for your care has been a profound privilege. As a former instructor at the David Geffen School of Medicine at UCLA and a provider at the UCLA Insomnia clinic, my goal is to provide more than just a space to talk—I offer the specialized, gold-standard steps necessary to create measurable, lasting change. At my practice, YCBT Services, I focus on working with adolescents, adults, and seniors who feel stuck despite their best efforts, specifically targeting generalized anxiety, social anxiety, OCD, panic disorders, and chronic insomnia. By addressing the underlying triggers that keep you on high alert, I am fiercely committed to helping you move beyond surface-level coping to reclaim your peace of mind.
